I have a Lenovo ideapad S400. I think it's like 7 years old. Recently got problem starting up. No respond. So i googled a bit and do this:
1. Remove battery and power adapter connection.
2. Press and hold the power button for 5-10 seconds.
3. Put back battery to laptop.
4. Power on again. Ok.
However the problem still persist after power off. I also can't power on the laptop if i removed the battery with only the power adapter connected. It should be able to power on without battery right? I have changed another power adapter to test and pretty sure it's not the power adapter problem as it works fine with another laptop.
Any idea what is going on? Battery kong? I think this battery also not ori and is a replacement i bought like 1-2 years ago. Probably not ori.
laptop can't start
